Most Popular Manual for 2007 GMC Sierra New Body

Fast shipping, nice product, fit perfectly.

Simply installed and removed, these mirrors make all the difference when towing our 33’ trailer. They easily adjust to allow the best views of both the trailer and surrounding traffic. I highly recommend this product.

fit is good.

I guess you get what you pay for. They were easy to install on my Tahoe. The driver side works well as I can see behind my Travel trailer. The passenger side just doesn't work for me. Its a flat mirror (Not convex) so field of view is very limited, I just cant find the right position for it. I also find it a bit confusing as there are now 4 different mirrors to focus on. I think the ultimate solution are the larger telescoping units. But of course they cost more and installation is more involved. I don't trailer that much so I can live with these. Oh, one little annoying thing is they whistle when the window is down(Quiet when the windows are up). I think its the sharp edge. On the plus side removal is quick so when you don't need them they come off easily when not needed.

The product fit good and looks good. They are just what I needed. The only thing is the brackets are plastic.

Great product and the best technical support I have ever experienced. Highly recommend etrailer

I bought both sides for my 2011 silverado and they look really good they look like they are factory mirrors install very quickly about 1 minute a side and they still allow the mirror to fold in if need be and they don't hit the side of the truck when folded in they fit my needs just fine the only complaint I have is the mirror itself could be bigger its about 1/3 the size of my factory mirror you have a decent blind spot when using them you just have to check yourself and its not a problem other than that they fit my needs well and come on and off quickly so they work really well if you don't tow 247 but it you tow very often like for a living I would recommend the full replacement ones cause they have less blindspot but if you tow every now and then they will suit your needs just fine I would recommend this product it you tow every now and then

The slip-on mirrors that I ordered fit snugly over the existing mirrors. As a Canadian, I was a bit anxious about ordering the mirrors from an American company in case they didn't fit, however your videos and sizing according to the vehicle year, and model made it reassuring that the product would work. I'm really happy with the mirrors, and look forward to using them for many years to come.

Product delivered quick to my house neatly boxed and instruction enclosed fits perfectly exactly what I needed thanks etrailer

put the new extension mirror on my mirror seem to strap on nice and tight but haven't had a chance to really get on the on the road and try them out yet

After reading lots of reviews on several mirrors, I decided to buy the K-Source Universal Towing Mirrors. Oh how I wish my truck could use the ones that slip over the existing mirrors! I was prepared for a fight, based on reviews, and boy did I get one! I truly needed a third hand when figuring out how to attach these. I was bound and determined that I could do this on my own. No mirrors were going to defeat me! I did ask my husband to come look at them. He started to help but I shewed him away. After a lot of words that don’t normally come out of my mouth and a few tears, the first one was on! Then I had to go do it again in the other side! I’m pretty sure the neighbors heard me yelling. But I persisted! Lo and behold, this 67 year old Grammy did it! It was clear they would not stay on by themselves, so I grabbed a couple of bungee cords and wrapped them around the housing and they aren’t going anywhere. I have left them on my truck. No way I’m going thru that every time we return from camping. I will take them off at the end of camping season. Delivery was really fast. I was disappointed that one box was brand new and the other was smashed and taped, an obvious return. I would have been very unhappy if there was a piece missing or if something was wrong since this was my first purchase with etrailer. Overall, the mirrors work, they do not shake and I find I don’t use the truck mirrors now. Very happy with my purchase.

Fast and free shipping! Mirrors are excellent. Could not be happier with them!

These mirrors are great quality very close to OEM . The installation went very well. I did take the door panel off to make it easier to get to the two lower fasteners, just to make sure I didn't loose the nuts inside door. There was very little vibration in the mirrors, I was a little worried about that by reading previous reviews. The mirrors held their positions, folded nicely when parked in tight spots. Everything said this is a great quality product

After years of replacing mirrors from other sources I purchased a pair of these. There fantastic, plenty of adjustments. Got covid on vacation, really sick and did not properly install mirror. Not broken but scratched badly from asphalt at 55 mph. Purchased a replacement, scratched one is my spare.

These mirrors are good, but not great. I bought these because nothing else fits my 2004 Ford Expedition. They allow me to see around my trailer much better than the factory mirrors, but the have a slight vibration driving down the road. They also make a very noticeable noise from the wind going between the factory mirror and this product. Finally, one of the straps came off when I tightened it a bit too much, but didn't break. The picture below was done in humor (I took my trailer through a drive through, thought it was really funny, and had to take a picture. The picture is a good shot of the mirrors.)

The company was fast and gave lots of updates for shipping. Once i received product my concerns were met. The straps are BARELY long enough to connect around my mirror. Once it is straped properly the tension on straps pulls them right out of the retaining clip. I ordered these because i have a 11 silverado just like what was in the product pictures. Save your money and get something else because theres no way these will make it down the highway they will barely stay on just sitting here. Kinda disappointed because i bout these for our first camping trip this weekend but these will not work. Seems like a good company just crappy product.

So-so construction and design. With one modification they're more than acceptable. The arms and straps will slip and loosen if installed on triangular or tapered housings. Mirrors that have backs nearly parallel to the mirror face, and have upper and lower mirror edges that are nearly parallel are not affected. Adding a peel and stick plastic wall hanger to a tapered housing will stop the strap from slipping and loosening. The ball and socket mount is good and tight, but the stud on the ball is loose in the arm. I think most of the jitter and vibration others report is from this sloppy clearance that the stud screw can't tighten enough. I'll be addressing that as well. A nice option for those of us that a) don't tow a majority of the time and don't want full time extended mirrors, and/or b) tow with multiple vehicles and prefer to have adjustability to fit our 'fleet'.

Fits good however vibrates considerably. was considering returning this item however I needed extended mirrors for my upcoming travels.

These worked great on my wife's Yukon. Installation instructions were clear and direct. They held up very well traveling 75 mph down the interstate; No jostling around or coming loose. I loved the additional two mirrors. Having the three total different angles while pulling a trailer was extremely helpful. Would highly recommend this setup.

They are fine for the price but hard to adjust the mirror itself after installation. I’ll be installing the bigger factory trailer mirrors pretty soon.

They appear to be as advertised, well made and should be easy to install. That may change once the rain stops and I am able to actually install them and then use them during the towing operation of our trailer. But i feel pretty confident they will be very helpful.

These adjustable mirrors where a great buy and very easy to install. I would highly recommend to anyone who need extendable mirrors.

The good: inexpensive; decent quality materials The bad: doesn't hold it position very well during extensive or high speed travel - you have to readjust at nearly every stop for gas on a trip. Conclusion: It is worth the money due to its fair price.

They are very easy to install and remove when parked for extended periods. Costumer service was very helpful with getting me the correct marrows.

Great product! I use them on all my trailers as well as my travel trailer. This is actually me second set...the first got destroyed by a hit n run and i could not live without them!
